Why do we use Helium gas in Flying baloon....if we say it is lighter gas then,Hydrogen gas is even lighter than itp

We use helium because it is is less dense. As helium is lighter than air, a helium balloon rises. Hydrogen is another gas lighter than air; it is even lighter than helium. Hydrogen is not used in balloons and this demonstration shows why.
Helium is a special gas called a Noble Gas, which means it doesn’t burn. When a match is held near a helium-filled balloon, the balloon pops. That’s it. But when a match is held near a hydrogen-filled balloon: BOOM! a real explosion. This is because hydrogen burns very easily. It combines with oxygen to make water vapor. Even though both balloons look the same from the outside, there may be something very different on the inside.

so you mean to say we don't use a hydrogen gas filled balloon only because it explodes very easily
The Castner–Kellner process is a method of electrolysis on an aqueous alkali chloride solution (usually sodium chloride solution) to produce the corresponding alkali hydroxide, invented by American Hamilton Castner and Austrian Karl Kellner in the 1890s.
